Pilot study of metabolic syndrome prevalence in students of the university institution Colegio Mayor de Antioquia en Medellín y la Universidad de Santander, Cúcuta, Colombia

Antecedents: Metabolic syndrome (Metsyn) is a condition that predisposes an individual to the development of cardiovascular disease, type 2 diabetes mellitus and its complications. Because its prevalence is increasing, it has become a global health problem that must be managed from early prevention and promotion of healthy habits. Objective: this study determined the prevalence of (Metsyn) in a group of young university students from the University Institution Colegio Mayor de Antioquia y la Universidad de Santander. Design and method: the research is descriptive and cross-sectional with a sample of 80 students (16 men and 64 women), between the ages of 17 and 32, apparently healthy. Using the IDF definition for Metsyn, variables such as waist circumference (WC), systolic and diastolic blood pressure (SP, DP), fasting glucose (FG), HDL cholesterol (HDLc) and triglycerides (TG) were measured. For statistical analysis, comparison between groups was performed with the non-parametric measure Mann- Whitney U test, significant level p<0.005 and the statistics program used was SPSS see 24. Results: MetSyn prevalence was found to be 5%, and individual analysis of its components or associated risk factors showed a higher prevalence for high WC and FG (38.89% in each), followed by the decrease of HDLc (27.78%). Conclusions: These findings are consistent with previous studies where MetSyn is estimated to be present in young adults according to IDF criteria. Based on this, it is recommended to adopt institutional measures that promote physical activity and healthy eating.

Knowledge, attitudes, and behavior related to HIV/AIDS in high school students in cúcuta, north of Santander, Colombia

Objective. Determine the level of knowledge, attitudes and practices about HIV and AIDS in adolescents. Methods. A correlational field study was conducted in 318 students of 13-21 years of age, between ninth to eleventh grade of two representative Educational Institutions of the city of Cúcuta, by probabilistic sampling. Validated CAP instrument (survey) and sociodemographic evidence were implemented for descriptive and correlational analysis. Results. There was a lack of knowledge about transmission, susceptible population and condom stability in 5-47% of the students, resulting in a low level for the knowledge dimension, in contrast with appropriate attitudes and practices. Conclusions. No association was found between age, sex, social stratum, family type or schooling with the dimensions of knowledge, attitudes or practices, being homogeneous in the sample, which projects it as a model group to contrast in future studies with other populations seeking to identify aspects that can be improved around global prevention strategies of the pandemic.

Prevalence of diabetes mellitus in patients with treatment for tuberculosis in a public hospital in Colombia

Introduction: Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis. Diabetes Mellitus is among the risk factors for the development of Tuberculosis. People with active Tuberculosis and diabetes can be negatively complicated by the results of Tuberculosis treatment, delaying the time of microbiological response which increases the probability of an unfavorable result and the risk of relapse, drug resistance, and death in some cases. Objective. To establish the prevalence of Diabetes mellitus and its correlation with risk factors in patients with Tuberculosis who underwent treatment in a public Hospital in Valledupar, Colombia. Material and Methods. A cross-sectional descriptive study was carried out in all cases diagnosed with Tuberculosis that underwent treatment in a public Hospital in Valledupar, Colombia. The diagnosis of diabetes was made with the use of a test to measure basal glycemia, the clinical histories of the patients, and surveys. All participants were surveyed for the evaluation of risk factors. Results. Of the 70 patients with Tuberculosis, 8 (11.4%) were diagnosed with DM. It was observed that the age> 40 years (p = 0.030) constitutes a risk factor for the TB-DM binomial; but there was no statistically significant difference with regard to sex, alcohol consumption, tobacco consumption, HIV, and body mass index (p> 0.05). Conclusions. The prevalence of Diabetes mellitus-Tuberculosis binomial in the Hospital studied corresponds to the figures established by the World Health Organization (WHO).

Prevalence and molecular typing of rotavirus in children with acute diarrhoea in Northeastern Colombia

After the introduction of the rotavirus vaccine, the number of rotavirus-associated deaths and the predicted annual rotavirus detection rate had slightly declined worldwide. Taking in account that in Colombia, Rotarix vaccine was introduced in 2009, the purpose of this study was to evaluate the presence of rotavirus A in children under five years who were treated for acute diarrhoea in Bucaramanga, Colombia and, moreover, to determine the genotypes of rotavirus present in those children. We performed an analytical cross-sectional study of rotavirus A in faecal samples from children up to five years of age. Stool samples were screened for rotavirus A using a lateral-flow immunochromatographic assay and confirmed using a VP6 sandwich ELISA. Genotyping of rotavirus A-positive samples was performed by PCR and sequencing of VP7 and VP4 genes. The overall prevalence of rotavirus was 30.53% (95% confidence interval [CI] 21.2 - 39.7). Most of the children with rotavirus (86.2%) had received two doses of the rotavirus vaccine. G3 strains accounted for the vast majority of cases (82.8%), followed by G12 strains (13.8%) and G3/G9 coinfections (3.4%). Among the P genotypes, P[8] was the most prevalent (69%), followed by P[9] (31%). The most common G[P] genotype combination was G3P[8], followed by G3P[9]. The main finding in this study was that rotavirus, in a Colombian region, is still an important pathogen in children under five years old, previously vaccinated. The results showed that different factors, such as kindergarten attendance, could explain the epidemiology and transmission of rotavirus in Bucaramanga.

Seroprevalence and risk factor associated with respiratory viral pathogens in dual-purpose cattle of Aguachica, Rio de Oro, and La Gloria municipalities in Cesar department, Colombia

Aim: The research was conducted to determine the seroprevalence and risk factor associated with respiratory viral pathogens in dual-purpose cattle of Aguachica, Rio de Oro and La Gloria municipalities in Cesar department, Colombia. Materials and Methods: The seroprevalence study was done from the random sampling (n=1000) of blood collected from 29 dual-purpose herds, located in three municipalities (Aguachica, Rio de Oro, and La Gloria) of Cesar department. The presence of antibodies against bovine herpesvirus type 1 (BHV-1), bovine respiratory syncytial virus (BRSV), bovine viral diarrhea virus (BVDV), and bovine parainfluenza-3 virus (BPI-3V) in the samples was detected by indirect enzyme-linked immunosorbent assay. Epidemiological data were obtained using a questionnaire administered to the owner or manager of each herd. Results: The overall highest seroprevalence was observed for BHV-1 (94.7%), followed by BRSV (98.6%), BVDV (35.2%), and BPI-3V (47.1%). Regarding the seroprevalence by municipalities, there was a statistical association (p<0.05) for BVDV; however, for BRSV, BHV-1, and BPI-3V, no statistical association was found (p>0.05) between seropositive values and the municipalities, indicating that animal was seropositive in similar proportions in the three municipalities. Female sex and older animals (>24 months) were a significant risk factor for BHV-1 and BPI-3V infection. Regarding the clinical signs, there was a statistical association (p<0.05) between the seropositive values of BVDV and most of clinical signs observed, except for abortion. Conclusion: This research confirms the high seroprevalence of the respiratory viral pathogens in nonvaccinated cattle within the study areas. Therefore, appropriate sanitary management practices and routine vaccination programs should be adopted to reduce the seroprevalence of these infectious agents.

High rates of exposures to waterborne pathogens in indigenous communities in the amazon region of Ecuador

Waterborne pathogens, associated with poverty and poor sanitary conditions, are a major cause of morbidity and mortality worldwide. There are limited data on the epidemiology of waterborne pathogens in indigenous populations living in the Amazon region. We did a cross-sectional survey in two indigenous Shuar communities in the Amazon region of Ecuador in which we documented the presence of pathogens representing different sources of environmental contamination of water. We detected protozoa and soil-transmitted helminths by microscopy of fecal samples and the presence of IgG antibodies to hepatitis A and Leptospira spp. in blood samples from individuals older than 2 years and collected data by questionnaire on sociodemographic factors and knowledge of infectious diseases. Seroprevalence for hepatitis A and Leptospira spp. were 98.1% (95% CI: 97.0-99.8) and 50.0% (95% CI: 43.3-56.6), respectively, whereas 62.6% (95% CI: 55.8-69.4) had enteric parasites in stool samples. In participants older than 6 years, eight of 10 had evidence of infection with or exposure to at least one of the pathogens studied. Although prevalence of pathogens varied by age, it did not vary significantly by gender, temporal migration, illiteracy, perceived morbidity, receipt of conditional cash transfers, water boiling practices, poor housing conditions, and anthropometric status. These findings indicate a high level of contamination of drinking water by human pathogens in these indigenous communities and the need for interventions to improve access to and use of clean drinking water in these marginalized communities.

Enkephalins and ACTH in the mammalian nervous system

The pentapeptides methionine-enkephalin and leucine-enkephalin belong to the opioid family of peptides, and the non-opiate peptide adrenocorticotropin hormone (ACTH) to the melanocortin peptide family. Enkephalins/ACTH are derived from pro-enkephalin, pro-dynorphin or pro-opiomelanocortin precursors and, via opioid and melanocortin receptors, are responsible for many biological activities. Enkephalins exhibit the highest affinity for the δ receptor, followed by the μ and κ receptors, whereas ACTH binds to the five subtypes of melanocortin receptor, and is the only member of the melanocortin family of peptides that binds to the melanocortin-receptor 2 (ACTH receptor). Enkephalins/ACTH and their receptors exhibit a widespread anatomical distribution. Enkephalins are involved in analgesia, angiogenesis, blood pressure, embryonic development, emotional behavior, feeding, hypoxia, limbic system modulation, neuroprotection, peristalsis, and wound repair; as well as in hepatoprotective, motor, neuroendocrine and respiratory mechanisms. ACTH plays a role in acetylcholine release, aggressive behavior, blood pressure, bone maintenance, hyperalgesia, feeding, fever, grooming, learning, lipolysis, memory, nerve injury repair, neuroprotection, sexual behavior, sleep, social behavior, tissue growth and stimulates the synthesis and secretion of glucocorticoids. Enkephalins/ACTH are also involved in many pathologies. Enkephalins are implicated in alcoholism, cancer, colitis, depression, heart failure, Huntington\'s disease, influenza A virus infection, ischemia, multiple sclerosis, and stress. ACTH plays a role in Addison\'s disease, alcoholism, cancer, Cushing\'s disease, dermatitis, encephalitis, epilepsy, Graves\' disease, Guillain-Barré syndrome, multiple sclerosis, podocytopathies, and stress. In this review, we provide an updated description of the enkephalinergic and ACTH systems.

Study of the energy use of biosolids from a chicken slaughterhouse wastewater treatment plant

The poultry industry in Colombia faces operational and environmental challenges, one of these is the integration of residual biosolids in other processes, which may generate a direct or indirect benefit within their production. This study shows the results obtained in the anaerobic treatment of the residual biosolid of the wastewater treatment plant of a chicken slaughtering plant; This biosolid is the result of the coagulation, flocculation and sedimentation process with ferric chloride, as main coagulant and possible flocculating substances in the process. The anaerobic treatment of biosolids is carried out in a CSTR bioreactor, with a capacity of 10 litres, inside the bioreactor the system is started, and different variables are monitored, such as pH, volatile fatty acids, alkalinity, sulphates, chlorides and chemical oxygen demand, which will determine the transformations of organic matter within the bioreactor, additionally biogas measurements resulting from anaerobic digestion are made, the gases analysed are methane, hydrogen sulphide, carbon monoxide and oxygen, which determine the quality of the biogas produced, together with the volume produced of biogas with respect to the volume of biosolids deposited in the bioreactor. This seeks to determine the productive capacity of the biosolids, to be stabilized and exploited energetically, considering that biogas is a usable biofuel and the resulting biosolid is a good raw material to produce organic fertilizers, destined to the agricultural production of animal feed.

Seroprevalence and molecular detection of Toxoplasma gondii among donors in a blood bank in Cúcuta, Colombia

Introduction: Toxoplasma gondii infection affects humans by producing several states of disease according to individual immunity ranging from asymptomatic carriers to severe disease. It is known that multiple mechanisms of transmission are possible including blood transfusions as an alternate route of infection. Little is known about the frequency of T. gondii infection in Colombia\'s blood banks. Objective: To determine the prevalence of T. gondii infection in blood donors of a blood bank of Cúcuta by serological and molecular diagnostic. Materials and methods: IgG and IgM antibodies against T. gondii were determined in serum by immunoassay test from 348 donors. The frequency of T. gondii DNA was determined by Polymerase Chain Reaction test (PCR) in whole blood from seropositive donors and interest variables were analyzed with information obtained from surveys during blood donor selection. Results: 134 out of 348 (38.5%) enrolled donors showed IgG antibodies against T. gondii; 2 of them (0.6%) had both IgG and IgM and in 2 out of 134 seropositive donors (1.5%) DNA of the parasite was detected in blood. A bivariate analysis indicated an association between seropositivity to T. gondii and being over 26 years of age (p= 0.020). Conclusions: The prevalence of T. gondii infection found in the blood donors of this study, suggests a significant exposure to the infectious agent that becomes relevant when parasitaemia is detected.

Study of the phytochemical kabuli chickpea (Cicer arietinum L) as an anionic coagulant for the treatment of water

The treatment of water by coagulation, flocculation and sedimentation, is a highly realized treatment throughout the world, and the most commonly used coagulant substances are aluminum sulphate, aluminum polychloride and ferric chloride; these substances produce a large quantity of sludge with high aluminum and iron salts, the production of these coagulants is carried out by complex chemical reactions, which demand a large amount of natural resources and produce sludge with high concentrations of these metals, and has shown that aluminum is toxic to plants and animals in different ways; This study shows the comparison of efficiencies between aluminum sulphate and a chickpea extract, which shows a very important coagulant activity. The turbidity and color removal efficiency were evaluated using an anionic coagulant obtained from Kabuli Chickpea (Cicer arietinum L) with an isoelectric point at pH of 3,7, its performance being compared with aluminum sulphate, for the treatment of synthetic water. Laboratory-scale synthetic solutions were prepared at initial values of 200 NTU. Parameters such as turbidity, color, pH and conductivity were measured. The Jar test was used to determine the optimal doses of coagulants, using 70, 80, 90 and 100 mg / L doses for the anionic coagulant and 60, 70, 80 and 90 doses of aluminum sulphate mg / l. The highest removal of turbidity and color was for the anionic coagulant with 98% and 94.71% with a dose of 90 mg / L and in the case of aluminum sulphate values of turbidity removal of 97.5% and of Color of 93.94% with the same dose, respectively. For the tests performed values were obtained within the range established by current Colombian legislation. It was concluded that the anionic coagulant can be used as a primary coagulant.

Acute effects of resistance and concurrent exercise on the lipid profile of postmenopausal women

The postmenopausal condition is characterized by a systematic increase in cardiovascular risk factors, including negative alterations in lipid metabolism. Physical exercise has shown beneficial effects in the regulation of lipemic markers in different populations; however, its effects are not well understood in postmenopausal women.The aim of the study was to determine the effects of resisted exercises (RE), concurrent exercises (CE), compared with a control group (CG) on lipid profile in postmenopausal women. Thirty-two voluntary postmenopausal women were randomly assigned into three groups; one group performed a RE session (n = 11), other group a CE session (n = 11) and control group performed flexibility exercises (n = 10). The basal lipid profile, body composition, muscular fitness were evaluated and the basal metabolic rate (BMR) was calculated before the study. The lipid profile was evaluated before, immediately after and 12 hours after the specific exercise session. The results showed that there was no a statistical significant difference among all groups in plasma concentration of total cholesterol, triglycerides and LDL, in any of the evaluation moments (p> 0.05). After 12 hours of exercise session, the CE group decreased more VLDL concentrations than the RE group and control group (p <0.05).The CE group increased significantly HDL concentrations in relation to the ER group (p <0.05).Therefore, it can be concluded that CE had more favorable acute effects on lipid metabolism than ER, prolonging its effect up to 12 hours after being performed in overweight postmenopausal women.

Antimicrobial resistance of Escherichia coli strains isolated from the bursa of Fabricius in broilers

The aim of this study was to determine the percentage of sensitivity or resistance of strains of E. coli isolated from asymptomatic broiler chicken against 18 common antibiotics used in poultry and in human medicine. In addition, strains that produce extended-spectrum beta-lactamases (ESBL) from a farm or slaughterhouses in the poultry area of Santander, Colombia. The circulation of strains resistant to beta-lactams, cephalosporins, aminoglycosides, quinolones and sulfonamides was determined, as well as antibiotics widely used in other non-farm environments. The content of the bursa of Fabricius was cultivated in McConkey agar obtaining 46 strains of E. coli. Susceptibility tests (n=18) were conducted to the isolated strains, and 91% of the strains were resistant to ampicillin and 80% to cephalosporins. The association of antibiotics with beta-lactamase inhibitors (ampicillin sulbactam and amoxicillin / clavulanic acid) showed 30% resistance. The double disc test was used to evaluate the presence of strains of E. coli producing extended-spectrum beta-lactamases (ESBL) confirming its presence in 63% of the samples. Results showed the presence of E. coli strains in asymptomatic chicken broilers with high antimicrobial resistance, including expression of ESBL.

Environmental and socioeconomic determinants of leptospirosis incidence in Colombia

Human leptospirosis is an infection that most often affects tropical countries. Since 2007, Colombia requires the notification of disease cases, enabling the observation of an increase in cases in recent years. The objectives of this article were to analyze environmental and socioeconomic variables and to evaluate their relationship with human leptospirosis cases. This is an ecological study on human leptospirosis cases aggregated by municipality and reported between 2007 and 2016. Spatial aggregation assessment was made using the Getis-Ord Gi method, and negative binomial regression was used to evaluate the relationship between environmental and socioeconomic variables with hu-man leptospirosis. During the study period, 9,928 cases of human leptospirosis were reported, and 58.9% of municipalities reported at least one case. Four hotspots of human leptospirosis, including 18 municipalities, were identified. The results of the negative binomial model confirmed the importance of the effects of education, poverty and some climatic variables on the decadal incidence rate of human leptospirosis. Our results confirm the importance of socioeconomic determinants such as social marginality associated with violence and education, as well as ecological variables such as rainfall, height above sea level and forest coverage on the incidence rate of human leptospirosis at municipal scale.

Analysis of labour market needs for engineers with enhanced knowledge in renewable energy in some European and Latin-American Countries

One of the main challenges related to the renewable energy labour market is that of human capital and as a consequence the educational profile of future employees is of paramount importance. Unfortunately, the skill level gained at University does not always fit with the practical needs of industry thus reducing the benefit-cost ratio of new employees and slowing down the transition to a green economy. Within this context, \'The Crux\' project co-funded by EU under the framework of the Erasmus + programme aims at improving the renewable energy engineering curriculum at different university levels in several Universities of Latin America and Europe. In order to better appreciate the potential impact of the project, a survey on the labour market need for specialists with enhanced knowledge and skills in renewable and sustainable energy technologies has been conducted in the related EU and Latin America countries. More precisely, 60 organizations have been interviewed and almost 70% of them are interested in employing engineers with enhanced knowledge on renewable energy in the next three years. The analysis has shown significant discrepancies between EU and Latin American organizations. In fact, while future employees in EU countries will be mainly related to solar energy and management, the former together with wind and biomass will represent the main renewable energy working sector in Latin American countries. Moreover, MSc level will be the most demanded in EU while bachelor education seems to satisfy the future industry requirements in Latin America. Despite each country having its own needs, the research carried out under this EU project confirms the potential of renewable energy education on the global labour market in the near future.

Infection dynamics of Cystoisospora suis (Isospora suis) on a pilot swine farm in Carabobo State, Venezuela

A research was done of the infection dynamics of the protozoan parasite Cystoisospora suis in lactating piglets at an intensive swine pilot farm in Venezuela. Over a 12-mo period (September 2015 to August 2016), 480 fecal samples were collected directly from the rectum in piglets in four age groups: 1-7 d (20 %); 8-14 d (47 %); 15-21 d (23 %); and 22-28 d (10 %). Stool samples were cultured in a 2.5% potassium dichromate solution and later processed by centrifugation-flotation. Cystoisospora suis was present throughout the study period with a 52.08 % overall average prevalence; values were highest in the second week of life. Meteorological variables (temperature, relative humidity and precipitation) had no effect (P>0.05) on variations in C. suis prevalence. Data from an epidemiological questionnaire were analyzed with a Spearman correlation test, identifying an association (P<0.05) between prevalence and the variables of on-site veterinarian, an intense disinfection protocol and use of 5% Baycox. Regional meteorological conditions are optimal for C. suis sporulation and year round maintenance of oocysts. This coupled with inconsistent control and hygiene protocols at the studied farm favored parasite survival and proliferation.

Joint association of urinary sodium and potassium excretion with cardiovascular events and mortality: Prospective cohort study

Objective: To evaluate the joint association of sodium and potassium urinary excretion (as surrogate measures of intake) with cardiovascular events and mortality, in the context of current World Health Organization recommendations for daily intake (<2.0 g sodium, >3.5 g potassium) in adults. Design: International prospective cohort study. Setting: 18 high, middle, and low income countries, sampled from urban and rural communities. Participants: 103 570 people who provided morning fasting urine samples. Main outcome measures: Association of estimated 24 hour urinary sodium and potassium excretion (surrogates for intake) with all cause mortality and major cardiovascular events, using multivariable Cox regression. A six category variable for joint sodium and potassium was generated: sodium excretion (low (<3 g/day), moderate (3-5 g/day), and high (>5 g/day) sodium intakes) by potassium excretion (greater/equal or less than median 2.1 g/day). Results: Mean estimated sodium and potassium urinary excretion were 4.93 g/day and 2.12 g/day, respectively. After a median follow-up of 8.2 years, 7884 (6.1%) participants had died or experienced a major cardiovascular event. Increasing urinary sodium excretion was positively associated with increasing potassium excretion (unadjusted r=0.34), and only 0.002% had a concomitant urinary excretion of <2.0 g/day of sodium and >3.5 g/day of potassium. A J-shaped association was observed of sodium excretion and inverse association of potassium excretion with death and cardiovascular events. For joint sodium and potassium excretion categories, the lowest risk of death and cardiovascular events occurred in the group with moderate sodium excretion (3-5 g/day) and higher potassium excretion (21.9% of cohort). Compared with this reference group, the combinations of low potassium with low sodium excretion (hazard ratio 1.23, 1.11 to 1.37; 7.4% of cohort) and low potassium with high sodium excretion (1.21, 1.11 to 1.32; 13.8% of cohort) were associated with the highest risk, followed by low sodium excretion (1.19, 1.02 to 1.38; 3.3% of cohort) and high sodium excretion (1.10, 1.02 to 1.18; 29.6% of cohort) among those with potassium excretion greater than the median. Higher potassium excretion attenuated the increased cardiovascular risk associated with high sodium excretion (P for interaction=0.007). Conclusions: These findings suggest that the simultaneous target of low sodium intake (<2 g/day) with high potassium intake (>3.5 g/day) is extremely uncommon. Combined moderate sodium intake (3-5 g/day) with high potassium intake is associated with the lowest risk of mortality and cardiovascular events.

Prevalence of gastrointestinal parasites in cattle and sheep in three municipalities in the Colombian Northeastern Mountain

Aim: The study was conducted to determine the prevalence of gastrointestinal (GI) parasites in cattle and sheep from three municipalities in the Colombian Northeastern Mountain. Materials and Methods: Overall, 200 fecal samples were collected directly from the rectum in cattle and sheep. The presence of helminths eggs and coccidial oocysts in fecal samples was detected using McMaster and Dennis techniques. Identification of eggs or oocysts was done on the basis of morphology and size of the eggs or oocysts. Results: The global prevalence of GI parasites was 56.3%. Regarding the prevalence by municipalities, there was no statistical association (p>0.05), indicating that the prevalence was similar in the three municipalities. The prevalence of parasitic infection was higher in sheep (63%) as compared to that of cattle (50.5%), but the difference was nonsignificant (p>0.05). The most prevalent parasites were Eimeria spp., Fasciola hepatica, and Strongylida order. Regarding the results for Eimeria spp., different degrees of positivity were observed, but there was no statistical association (p>0.05) with respect to the age group. Likewise, there was no statistical association (p>0.05) between the prevalence for Strongylida order and F. hepatica with respect to the age group. Conclusion: Cattle and sheep in Colombian Northeastern Mountain were infected with helminths and coccidia. The prevalence values of GI parasites were moderate in both species warranting treatment. The presence of F. hepatica represents a risk factor to health public. Future studies are required to evaluate the parasitic dynamics throughout the year and the impact on animal production.

Analysis of the intellectual structure and evolution of research in human-computer interaction: A bibliometric analysis

Bibliometrics is the application of quantitative models and methods for the understanding of research disciplines. The main concepts that are applied within the development of this type of analysis are associated to the analysis of networks and include the links, number of links and force of link within the networks of co-occurrence, co-citation, co-authorship and bibliographic links. Under these concepts and in order to visualize the evolution of human-computer interaction (HCI), a bibliometric analysis of the published literature is developed in order to know the characteristics of this body of knowledge and its development over time, understanding the evolution and trends within the research disciplines requires the combination of methods and tools that guarantee equality and replicability within these exercises. In that context, this article implements analysis is based on a systematic and exhaustive search strategy of the evolution of the HCI literature, using a combination of quantitative methods, which includes a quality analysis for the delimitation of the simple analysis of the identified publications.
